Behold! Let me tell you a bit about French GUILLOM, since you seem to be interested! French GUILLOM is something ethereal! Something that cannot be described to words! It's...it's simply unanalyzable! You see, the thing about French GUILLOM is that we only know little to nothing about this "entity" as you call it. We know for certain:

1. it's French.

2. It can speak French, but has made the impression to us, GUILLOM researchers, that it's too withdrawn to have the courage to speak French, so it weirdly acts like it's Spanish instead (which we, GUILLOM researchers, highly doubt).

3. It is an object-sexual individual, from many precise investigations and reports that delineate instances of him trying to insert his penis into the structure of the Eiffel Tower, perhaps because it thought it could impregnate it.

4. It's intangible, which means it's unable to be touched and doesn't have a physical presence, though we are aware of his presence because of a special device we created called the G.D, and no, it doesn't stand for Gaucher Disease, but GUILLOM DETECTOR.
5. It appears to be a hermaphrodite, meaning it has both male and female sex organs! We were surprised to discover when we were attempting to scrutinize its existence using the GUILLOM DETECTOR, it isn't a male, for we've also found that it has a vagina and 6 breasts! Fascinating, isn't it? GUILLOM truly is an astounding creation of nature! We've never seen something like it before, in our entire lifetime!

Guillermo 

One of the sweetest person’s I know. He is so caring, sweet, kind, and one of a kind. If you ever find a Guillermo, he’s a keeper ❤️ He will always be there for you and you will find reasons to fall in love with him more and more each day. He might come off as the girl of the relationship but that’s okay. I love him so much. So ladies, you better stay away. He’s MINE! But yeah a Guillermo is the best.
Guillermo is mine.
